Magnetricity

"Magnetic current is the same as electric current. Current is [actually] a wrong expression. Really it is not one current, they are two currents, one current is composed of North Pole individual magnets in concentrated streams and the other is composed of South Pole individual magnets in concentrated streams, and they are are running one stream against the other stream in whirling, screwlike fashion, and with high speed." -- Edward Leedskalnin, stone mason, 1945

Researchers have discovered a magnetic equivalent to electricity: single magnetic charges that can behave and interact like electrical ones.

The work is the first to make use of the magnetic monopoles that exist in special crystals known as spin ice.

Writing in Nature journal, a team showed that monopoles gather to form a "magnetic current" like electricity.

The phenomenon, dubbed "magnetricity", could be used in magnetic storage or in computing.

Magnetic monopoles were first predicted to exist over a century ago, as a perfect analogue to electric charges.

Magnetic Monopoles Detected Again

Dirac and Leedskalnin confirmed again. Last month scientists confirmed what Leedskalnin already knew -- magnetic monopoles exist.

Other scientists are just now repeating the discovery: Large-Scale Cousin Of Elusive 'Magnetic Monopoles' Found At NIST.

ScienceDaily (Oct. 8, 2009) — Any child can tell you that a magnet has a “north” and a “south” pole, and that if you break it into two pieces, you invariably get two smaller magnets with two poles of their own. But scientists have spent the better part of the last eight decades trying to find, in essence, a magnet with only one pole. A team working at the National Institute of Standards and Technology (NIST) has found one.

In 1931, Paul Dirac, one of the rock stars of the physics world, made the somewhat startling prediction that “magnetic monopoles,” or particles possessing only a single pole—either north or south—should exist. His conclusion stemmed from examining a famous set of equations that explains the relationship between electricity and magnetism. Maxwell’s equations apply to long-known electric monopole particles, such as negatively charged electrons and positively charged protons; but despite Dirac’s prediction, no one [except Leedskalnin and the scientists last month] has found magnetic monopole particles.

Now, a research team working at NIST’s Center for Neutron Research (NCNR), led by Hiroaki Kadowaki of Tokyo Metropolitan University, has found the next best thing. By creating a compound that under certain conditions forms large, molecule-sized monopoles that behave exactly as the predicted particles should, the team has found a way to explore magnetic monopoles in the laboratory, not just on the chalkboard. (Another research team, working simultaneously, published similar findings in Science last month.)

Magnetic Monopoles Detected

Physicist Paul Dirac was correct about the Expanding Earth and now it seems he was also correct about magnetic monopoles.

Science Daily: Magnetic Monopoles Detected In A Real Magnet For The First Time.

ScienceDaily (Sep. 4, 2009) — Researchers from the Helmholtz-Zentrum Berlin für Materialien und Energie have, in cooperation with colleagues from Dresden, St. Andrews, La Plata and Oxford, for the first time observed magnetic monopoles and how they emerge in a real material.

Results of their research are being published in the journal Science.

Magnetic monopoles are hypothetical particles proposed by physicists that carry a single magnetic pole, either a magnetic north pole or south pole. In the material world this is quite exceptional because magnetic particles are usually observed as dipoles, north and south combined. However there are several theories that predict the existence of monopoles. Among others, in 1931 the physicist Paul Dirac was led by his calculations to the conclusion that magnetic monopoles can exist at the end of tubes – called Dirac strings – that carry magnetic field. Until now they have remained undetected.
